Competition-GradeKnee Sleeves

Official Sponsor

Get The Ultimate Workout Weapon, Assassins.

NEW from RockTape, the ultimate weapon in workout domination – Assassins. An entirely new generation of knee sleeve, Assassins provide uncompromising support and protection allowing you to slay reps and crush WODs all while keeping your knees supported and protected.

Assassins are are available sized small through extra large, with two thickness options – 5mm and 7mm – for moderate (5mm) to extreme (7mm) support.

Built For Competition

Assassins are designed with the unique needs of athletes in mind, and unlike sleeves from other companies, are much more than a re-purposed medical support.

The result is a pair of knee sleeves that are suitable for the most grueling workouts, lifting events, and obstacle course races – yet comfortable enough for the weekend warrior.

Uncompromising Value

Workout gear should be reasonably priced and available to anyone. We also believe that every athlete deserves two sleeves – that’s why Assassins are always sold as a pair.

When stacked up next to the competition, Assassins quality and price can’t be matched.

Pure Performance

Built extra tall, Assassins help ensure proper stability and tracking of the knee, and can often dramatically reduce non-specific knee pain, particularly during squats.

This also keeps sleeves in place – preventing excess slip and movement during workouts, a common complaint of competing sleeves.

Nearly Indestructible

If any pair of Assassins fails to carry out their purpose, RockTape offers the industry’s only one-year warranty against defects and premature failure from date of purchase.

Sizing

Measure the circumference of your knee around the center of your patella.

Assassins start very snug and can take a few sessions to break in.

If you measure on the higher end of a size, we recommend ordering the next size up.

So far so good. I feel a ton of support when lifting very heavy.

Yeah, I'm 6"8, I have legs like tree trunks... and these are hella tight. But I like the wear you can rest it on your shoe when your not working it. I use one on my bad knee... It's quick and fast to get on and off and it provides TIGHT support. I'm a big fan.

These sleeves WOULD be great if they didn't fall apart. First few sessions with them were fantastic, but the inside basically split and broke apart all through the support area.
I'd say it was a one-off defect, but my training partner bought a pair and the exact same thing happened to his.
It's a shame, had they have lasted more than 3-4 training sessions they'd be an easy 9/10

The measurement is off. It's way off. For male, unless you have a pin-leg, get XL and bigger. Start from there. I bought large to be safe, to get a tight fit, but I can barely get it on.

I have really messed up knees, so I wanted something with just a little extra support that would be versatile without spending a fortune for a pair. Rocktape seemed to fit the bill well so I gave them a shot. They're comfortable, excellent support for these bad knees (I LOVE squats, and they work for it) and they look cool (I got the skulls!). HOWEVER..... The sizing is a little inadequate. I don't have huge legs and my knee measured out to 16.25". The XL set is 14 1/2 "and above". If I'm dried out and not holding water I'm fine, although they're snug. But, if I have some water retention or or I'm refeeding then they don't really fit at all, which is a bummer because they're so supportive. Hopefully they'll break in really well and be a little more lenient on the sizing.

These knee sleeves are by far my favorite ever used!! They are comfortable and give me great support on my heavy lifts, which I'm doing more and more of all the time. Assassins are a game changer and if you haven't used them you most definitely should!
